Thanks Matt.

Well, the reason why we are brining in the fill/Class 5 is because the ground is a bit uneven and we can't dig down/scrape to level because the water table is so high, so we do worry about saturated ground heaving. Its not MUSHY wet, but we have hit water at 18-20" in spots of our yard during wet years. We don't know how wet would be considred too wet/saturated to risk heaving. A very dry year would be different - an average year, maybe 2.5-3' would start to seep water. We have our well at 7' with a flowing underground stream.

I checked into "crusher run" (from your old post) and none of our gravel guys have it, except the recycled ground concrete. We do intend to have the compacted Class 5 at 6" where the pool sits and 1' out then in the remaining 1' out slope down to about 4" at the concrete edging so it runs off and then ditch so it all runs into the woods to the south.

The bottom rails and base plates are alluminum with some type of coating, the Mfg claiming a lifetime guarantee against corrossion, but this guy indicated that alluminum is the worst. (!!??)

Well, we have the pool now, so we will just be extremely obsessive about compacting and being level. Where does one get 2" blue styrofoam, the local Home Depot or Lowes? A special type of styrofoam? Pre mfg pool pads were too expensive for my taste, sand cheaper. Would styrofoam go over sand or without?

Thanks guys. This waiting for the road truck load limits to go off for our fill and sand is just killing me (could be anytime up to the 3rd week of May!) I want to get started NOW and am so jealous of everyone getting their pools started and opened.
